In this building, we never use the existing construction methods such as disassembly, destruction and newly construction to ensure the eco-friendly building and to decrease of waste disposal. We make customers feel newly by using minimum materials, pursuing the 'Best Design Using Lower Material' slogan and remodeling the building partially. The line is the most informal type one which is lack of intention. This line formation is harmonized with self-efficiency and completeness that are not required for unnecessary things, and simple unification which has not alternatives or obstacles.

This study aims to develop a sulfur-using denitrification process which is possible a renovation to advanced treatment plant submerging a simple module in activated sludge aeration tank. At first, the impact factor of sulfur-using denitrification was appreciated by the batch test. Secondly, reflecting a dissolved oxygen effect of sulfur-using denitrification that was confirmed by the batch test, in a continuous nitrification/sulfur-using denitrification, high-rate nitrogen removal reaction was induced at optimum condition controlling DO concentration according to phases. Also, inside and outside of sulfur-using denitrification module was covered with microfilter and the module was considered as an alternative of clarifier. Result of batch test for sulfur-using denitrification, $NO_2{^-}N$ was lower for consumption of alkalinity and sulfur than that of $NO_3{^-}-N$. These results revealed the accordance of theoretical prediction. In continuous nitrification/sulfur-using denitrification experiment, actual wastewater was used as a influent, and influent nitrogen loading rates were increased 0.04, 0.07, 0.11, $0.14kg\;N/m^3-day$ by changing hydraulic retention times. At this time, nitrogen loading rates of packed sulfur were increased 0.23, 0.46, 0.69, $0.93kg\;N/m^3-day$. As a result, nitrification efficiency was about 100% and denitrification efficiency was 93, 81, 79, 72%. Accordingly, nitrogen removal was a high-rate. Also the module of sulfur-using denitrification covered with microfilter did not make a fouling phenomena according to increased flux. And the module was achieved effluent suspended solids of below 10 mg/L without a clarifier. In conclusion, it is possible a renovation to advanced treatment plant submerging a simple module packed sulfur in activated sludge aeration tank of traditional facilities. And the plant used the module packed sulfur is expected as a effective facilities of high-rate and the smallest.

The number of schools which have passed 30 years after the construction takes up 30% (5% falling to class D and E) in Korea. So, the offices of education across the nation conduct large works for the expansion, improvement and renovation of the school. But as the work takes a lot of time, the work is also conducted while the students are studying at the schools. The work at the school causes the noise, dust, vibration as the school often has the reinforced concrete structure. So, as the windows are closed to prevent the nuisance from hampering the education, the problems related to the illumination, ventilation, and control of humidity and temperature are give damages to students studying the school buildings. Actually, as the current renovation or expansion is conducted across the nation due to the implementation of the new education system and the resulting integration and construction of hub school, specialized school, meister school and it causes a lot of nuisance to the learning students and others, there are a lot of complaints from concerned people. Accordingly this study suggests the method of evaluating the factors which affect the learning environment such as the noise, dust or fine dust and reducing the nuisances to the level proper for the learning environment when the existing school is expanded, improved or renovated.

Ihis landscape design was proposed for the Remodeling for the National Theater of Korea Competition. Today, the National Theater of Korea, located in Jangchoongfong, Joong-gu, Seoul, asks plans for renovation. The landscape design for the remodeling of the theater is conducted as part of comprehensive programs for its renovation. The Government sought design proposals through a design competition in April, 2002. The authors proposed a landscape design for remodeling the National Theater of Korea and won first place in the competition. The landscape design covers the following a survey of the present status, a site analysis, a schematic design, and design, development. In the authors'design, heavens, humans, earth and nature are symbolically expressed within the site. The outdoor spaces of the National Theater of Korea are organically composed of the following low spaces : 1) a field of creation; 2) a field of recreation; 3) a field of meeting; and 4) a field of contemplation. The field of creation consists of a main entrance, spaces for public performance and plays, spaces with symbolic water features, and resting areas. The field of recreation is composed of various exhibition spaces. The field of meeting consists of traditional Korean-style gardens and an outdoor cafeteria. The field of contemplation features lawns, grasses and trees, and provides an area for pedestrian strolling. The outdoor spaces of the National Theater of Korea would produce an atmosphere suited to a cultural and artistic place. In the spaces, people would perceive a unique sense of place through various types of fountains, pergolas, columns, walls, light poles and bollards. An example of the true meaning of a cultural space and a resting place is provided in these spaces. The renovated National Theater of Korea would be a new type of theater with regional context, cultural meaning, spatial identity, various amenities with symbolic images, function and beauty.

The goal of This study is to predict medical fee by accidents at home and the factors of accidents, and also to suggest the conditions of housing adaptations for elderly people. As the result of in-house accidents, on average 2.97 million Korean won was to be spent for medical care. Furthermore, 2808 billion Korean Won, which was predicted by multiplying the number of older people with the reported accident rates of 2.0% by the National Health and Nutrition Survey 2005, can be estimated to pay on medical care in 2005. And in addition it is analyzed on residential conditions and 65 cases of elderly housing. According to the 65 safety problem cases, it examines that in-house accidents of older people generally happen at the steps, toilet and bathroom. It is necessary to adapt physical conditions and it is more effective. As the result of research, medical fee by accident at home has been increasing and also it could be predicted to spend 280,800million won in 2005. To reduce medical fee, it is necessary to promote physical environment by renovation. When be decided to renovate a housing, we know that it is more effective to use a checklist of space using at home. And also it is suggested to amend a checklist with other factors including physical conditions and health condition and so on to promote a correctness.

This study explored what impacts can be brought to students, teachers, schools, and community by the improvement of physical environment of school spaces. For the purpose, we studied 5 schools (2 elementary and 3 middle schools) who took part in the Happy School Project funded by the Ministry of Culture, Sports, and Tourism in 2008. Ten series of Focus Group Interviews were carried out with a sample of 28 students and 20 teachers who experienced both before and after the school renovation project. The analysis of the interview data revealed that although the project was concerned with a part of school space such as restroom or reading room, it could bring multiple effects such as following: First, the students addressed that they felt "good" about school environment, which led them to feel good about their "schools." This change was found out to bring about more positive attitudes towards a school in general, public manners, peer relationships, emotional well-being, and learning. Second, the teachers became to value more their principals' leadership, being more satisfied with their work environment and more concerned about management of school facilities, and happier with students in terms of teaching and guidance than before. Third, all the 5 schools seem to go through a noticeable change in terms of a school climate and ethos in a more positive and harmonious way. Finally, 'spread', 'promotion', and 'openness' effects were discussed with regard to the relationships between the schools and local community.

This study has been conducted to perform the survey on the ecological systems, scenary, and water quality change for agriculturally purposed drainage channels constructed with the application of environment-friendly methods and thus to evaluate the environment-friendly redevelopment effects of them. The main results of this study are as follow: 1. The channels not looking good aesthetically before redevelopment had changed into graceful scenic views from the aspect of landscape architecture as natural-type gently waterside to the channel and naturally-looking water stream. In the village parks developed for the rest of residents, an enough view was secured and thus a wide prospect scope could be obtained. 2. The flora in the channels have increased to 35 families and 82 species from 19 families and 32 species before renovation. As the growth speed of them are slower than externally-brought plants, they can cause some risks to the stability of land slope, including scour by erosion. From that reason, it is necessary to adequately combine the species of the plants both natively growing there and externally-brought planted. 3. In case of water quality, it turned out that, from more than a year after redevelopment, plants began to take roots and the water quality improved. On the contrary, there have been some cases, partly found, that aggravated the quality of water due to the causes like as retention of floating matters by withered plants or plant bodies after the growth of plants in the channels under survey became active, and therefore it is judged that a periodic maintenance of waterways is needed. 4. In case of fishes, all species before renovation have revived, and the population and the number of species have increased after works the formation of puddles in the channels. In waterside grasslands, amphibia and reptiles have not only increased but also been diversified.

The vernacular houses with 田-shaped floor plan at Gangreung have been played important roles in tracing the vernacular living cultures including housing life. But due to the adoption of convenient facilities in vernacular housing lives caused by modernization and urbanization, many changes and transformations have happened at residential space of vernacular houses. This thesis targets to extract basic data to prepare and prevent various problems in process of renovation, extension and function change as installing housing life facilities, and to identify the changes and transformations of them to prepare the proper balances between their original form preservation and residents' convenience living. The results are as follows. The inner wall removal of rooms, the fuel change of cooking and heating, the leveling change of kitchen floor made possible the sedentary lifestyles. And its residential rooms were transformed from two row to one row by inner wall removal, the fuel heating change, the heating method change and the heat insulating materials. The residential extension materials were changed from the traditional materials such as soil, wood, etc to the modern materials such as cement block or brick, sandwich panel, etc. And the modern materials were used and attached to widen residential spaces to the vernacular house because of the easiness of execution. So, it is necessary for 田-shaped floor plan vernacular house owners to distribute printed execution guide book to prevent and minimize the various problems to be shown by extension, renovation and function change.
